Re: Weak S/PDIF output, known but non supported issue????

2004-02-21 by Mike-E

I know I can nomralize. I know the digital signal is better and has 
headroom. But I also know that E-mu knows it's a "bug" in the xx-7.

As I mi the S/PDIF with other signals (analog, VSTi, analog out of 
the XL etc.), I have to turn all other signals down, because of the 
weak signal of the E-mu... and that's not the way it should be.

It's a nice explanation... but it's not everyone's reality.
